The Porter hypothesis suggests a double dividend in the sense that environmental policy improves both environment and competitiveness. The suggestion received strong criticism from economists mainly driven by the idea that if opportunities for higher competitiveness exist firms do not have to be...

Recent research developments in common-pool resource models emphasize the importance of links with ecological systems and the presence of non-linearities, thresholds and multiple steady states. In a recent paper Kossioris et al. (2008) develop a methodology for deriving feedback Nash equilibria...

Dynamic problems of pollution and resource management with stock externalities often require a differential games framework of analysis. In addition they are represented realistically by non-linear transition equations. However, feedback Nash equilibrium (FBNE) solutions, which are the desired...
